[PATCH 5.3 076/344] gpio: madera: Add support for Cirrus Logic CS47L15

[Greg Kroah-Hartman]

From: Richard Fitzgerald <rf@xxxxxxxxxxxxxxxxxxxxx>

[ Upstream commit d06be8bc290aa255b9fd8602e60fb9f487aa0f48 ]

As the gpio is common to all madera codecs all that is needed
is to setup the correct number of GPIO pins for the CS47L15.
